Players and FBI Agents, Law & Order: 2073 Options

[Wolfgar]

I am about to embark on another Shadowrun game, my gaming groups' third. SR4A. Last time they played runners in Sydney, and I ran into a problem- the players were facing moral dilemmas every time they were asked to kidnap or harm someone. I wanted this to happen to some extinct, but the players were getting bummed out. So, this time I want to allow my players to have the moral high ground, and only tempt them with treachery, not out right reward them for it.

Hence, the players are agents of the Federal Bureau of Investigation, based in Seattle. Instead of plotting runs, they will collect evidence and solve mysteries, track down killers and kidnappers, foil terrorists and deal work with Knight Errant on daily basis.

I've still got a few month to prepare, but I have my players sold on the above pitch. Two players have pitched me character ideas- A phys adapt Drake, fresh out of the academy, and a young hacker, "such a good criminal the FBI hired me."

What do you guys think? Can it be done, has it been done? You guys helped me out a lot with my last game, I appreciate any ideas.
